those termed crown corks.

More particularly the invention pertains to means for feeding the sealingdisks 'of cork or similar-material of the closures to the assembling. devices of the machine.

In feeding sealing disks of cork or the like to cap assembling machines, many diflt culties have been experienced owing to the fact that, first, said disks vary in their thick? nesses to some extent second they are very light-in weight, and, third, they are likely to take'a curvedor-bent shape when being prepared or treated before they are put upon the assembling machine; vIn'the latter machines, a mass of sealingdisks is'placed' into a hopper,-wherefrom'it has been" the practice toj feed themusually through a chute into a tube that leads to the transporting means-which conveys the sealing disks, one after the other to the assembling elements of the cap makingmachines While it'is comparatively; easy to cause thedisk'sito pass from; the-hopper proper into the chute above-mentioned,"'it has been found almost impossible topass them from the chute. into and stack them properlyin thetub'e-lejading to the transporting means of the assembling machine." The troublesfarise i'nflthis last namedoperation mainly. due to the fact that the sealing i disks are very light in' weight, and the difficulties whieh are expe rienced withinthe hopper proper are"ordi-,

narily due to thevarying thicknesses and. shapesof said '(lisksf In}; pri'Or'Ui s." Patent Nb; 1,200,918,1'

have disclosed a somewhat similar feeding attachment, the same embodying a hopper and a chute communicating with the discharge opening thereof, said chute being adapted to deliver the disksto an oscillating stacking tube; audit-is the object of the presentinvention to dispense with thesaid in section;

chute and with thelmeans for 'keeping the I disks therein continuously in finotioii, To

' this end, the invention consists'essentiallyin feeding the disks directly- 'fromthe :hopper to a horizontal portion of the oscillati-ng stacking tube, which portion is provided" with a sufliciently large-and elongated "openmg reciprocating through the base of [the hopper. this manner, the construction andoperation of the feeding attachment is greatly simplified and its cost materially re-Y ducedJ The' contrivan'ce, furthermore, is

more eflicient and'more rapid in'its action" than is the case of the apparatus set forth in the-aforesaid'Letters Patent;

With these and other objects in 'view, which will more fully appear as the nature of the invention is better understood, the same con's1sts 1n the combination, "arrange-J ment and construction of parts hereinafter fully described, pointed out inthe'app'ended claims and illustrated inthe accompanying drawings, it being understoodjthat many changes may be made in the size; and proportion of the-several parts and details' of' construction within thescope of the ap pended-claims without departing from the spirit or sacrificing any ofthe advantages of' theinvention.- s I I p l One-of the many possible embodiments of the invention is illustrated inftheiac'com panying drawin gs, in which F'gure 1 isja side elevation,'partly iin sec.

tion, of a feeding attachment constructed-fin accordance with the present" invention;

' Fig. 2 is a lfront elevation thereof,

s Fig. 4*i11ustrates'a medifie etai' v vertical section taken on the Similar characters of reference designate corresponding throughout the several views.

. Referring tojthe drawings, l0 designates 1 I a hopper, '1 generally of conicalform, j-and terminating at'its lowerreduced end in an posed tube 13 The hopper 10 isimounted upon a suitable standard or framelfifin a plane a substantialdistance above the table elongated'open'ingll, thesame being round-l' ,1 ed to. receive and provide a bearing. for the 1 horizontal portion l2 of avertically disg 1'05 3' 14,; of the assembling machinef(not shown).

As one means or; attachment, the {hopper mayhave secured thereto or integral therewith a. plate or fiange16, having a threaded extension 17 passing through the frame 15,

and held thereto for example by means of a nut 18. A bolt 19;moreover, extends outwardly from the plate 16 through a slot 20 of the frame," permitting the hopper as a whole to betilted through an angle of 90 and about the horizontal portion 12 as an axis. In this manner, any ,remaining cork disks may be readily removed from the said hepperpand, whenthe latter-is in an operatiye position, it may be secured therein by tightening a winged nut 21 mounted about said bolt 19.

The'outlet ll in' the bottom of the hop: per :10 is designed to be-closed'by thehorizontal tubeportion12, the upperportion of which, whereit cooperates with thebottom of the hopper, being provided with an, elon: gated horizontal opening 25 of suflicient size to receive the disks contained in the hopper, and in .any positionwhich the said disks-may assume. .Furthermorathe lower w-allofthetube portion 12 isprovided with a plurality of perforations of sizesuflicient only to pass cork chips and foreign materialto be discharged therethroughas the same is received from thehopper 10 through the opening 25. The horizontal tube portion 12 passes, entirely through the base of githe'hopper 10 as well asthrough the plate 16,.and extensionl'l, and terminates in a slottedblock or the like27. The latter is adapted to be engaged ,by a rotatable pin or roller'28. eccentrically disposed with. respect to the longitudinal axis of thesaid horizontahportion 1 1. 1 A driving pulley 29, actuated by 'some suitable source of power (not shown),isuarra nged to rotate the said pin 28and thereby effect a reciprocation of said horizontal portion 12 of the tube .13. For this purpose abearing' 30 is amounted upon the table 1 1 of the assembling-machine and is adaptedto receiyeQthelower spherical end 31 of the said tube 13,. which tubeis curved at its upper end and merges into the horizontal portion .12 aforesaid. Or, as illustrated in Fig. 4, the vertical portion of the tubemay' be maintained stationary and :terminate shortly before the horizontal port-ion in a flared opening 35, into which the curved end 36 of the horizontal portion discharges.

In this manner, the-reoiprocatoiy movement communicated to the horizontal portion12 serves. to feed the disks thereto and totheverticalportion 13, and-to them in ;.-the latter in horizontal position from which they are removed through the-lower end by 1 suitable transporting means (not shown) and operating in conjunction with the assembling machine (not shown). It wilhbe noted that the upper wall of the tubei pprtion 12 is freely open to the, contents of the hopper, and that there isno intermediate sorting 'orvstacking device or means for keeping the disks in motion be tween said hopper and the said tube. The construction set -forth-herein affords an extremely simple and also eflicient means for effecting the stacking of the disk members which aremerely dumped into the hopper 'without any particular regard totheir position relatively tqtube 13.
